Stupidly Obscure Programming in a Troubled Time

Since obsessively underlining passages in a tattered copy of
Goodbye to Berlin
hasn't proven to be the uplifting diversion I was hoping for, I
resolved to bash my head against some really complicated scala code that I'm not
qualified to write and that nobody is asking for either.

So that this exercise in self-abuse could pass for a reasonable use
of my time - but not too reasonable, since that would be a giveaway -
I decided to link it to an existing, longstanding obsession of mine:
paradigms and constructs for concurrency.
